MOTORi-TRUCK TURNTABLE.

App1ication -1ed May 14, 1925.

Toall whom tammy concern:

Be it known-that I,`EARL L. GLAZE, a citizen of the United States,residing at Chilesburg,v in the county of Fayette and Stateof; Kentucky, have invented certain theV provision of a turn table that is portable in nature lso thatA itY may be transported to anyplace. where it isdesired to turn motortrucks such-"for instance as where buildings are being erected, ory roadsmade or repaired,

the purpose being 'to obviate the, necessity of; turning the truckfin the roadway thus.

blocking traffic, and providing a turn table that is reasonablek in cost of manufacture, effective in operation, and Athat may be readily knocked down for transportation and set--y ting up-in the location needed.

The construction and operation and advantages of the invention will be described in detail hereinafter and will be found illustrated in the accompanying drawings, in which Figure 1 is a top plan view of the imy proved turn table,

Figure 2 a side view,

Figure 3 a cross section on a plane indicated by the line 3 3 of Figure 1,

Figure 4 a similar view on a plane indicated by the line 4 4 of Figure 1.

Figure 5 a sectional detail on the line 5 5 of Figure 1,

Figure 6, a sectional detail on a plane indicated by the line 6 6 of Figure 5,

Figure 7, a detail sectional view on the line 7 7 of Figure 1,

Figure 8, a detail view partly broken away and in section showing means for applying rollers to the frame for transportation, and

Figure 9, a sectional view on the line 9 9 of Figure 8.

In the drawings, similar reference characters are used to designate corresponding parts throughout the lseveral views.

The improved turn table is mounted on a base frame comprising a square frame having its four sides, designated 1, made prefer Serial No. 30,328.

ably of channel steelV andconnected at its corners by anglemembers 2 securedto the sidesl by meansof bolts 3 that'permit dismemberment of said members 1 and 2 when it is desired to move the turn tablel 4 indi-I cate braces for the corners of the square frame and secured to the sides 1 lby means oftbolts 5, said angle braces 4 also formed of channel steel. A circulartrack is mounted inside of the square frame and comprises two semi-circular members 6 also made of channel steel and having the flanges ofthe beam extending toward vthe center of the circle formed by said members 6, said Vmem-Y bers 6. beingsecured tothe frame by means ofboltsf? engaging said'members 6 `and the beams 1 and braces 4. The width of the beams forming the members 6 is preferably greater than the, width of the beams 1 andV braces 4, the preferred proportions .being a ten'inch channel beam for the members,

and eight inch channel beams fory the meme bers 1 andv 4, thus AIna-king the members 6 extend two inches above thev members 1 and 41andpermitting the. beams' 1 to act as rests for the-.upperfendsrof skids V8 forming inf clined approaches to the turn table on the road level.

The turning part of the turn table 1ncludes two tracks designated 9 that are preferably made of channel beams and having a flange along each of its longitudinal edges, said flanges being designated 9a. The tracks 9 are connected together by means of arcuate bars 10, preferably made of channel steel, and 11 indicate shorter bars of channel steel secured to the tracks and spaced from the bars 10.

Secured to bars 10 and 11 are journal boxes 12, said journal boxes having ears 13 through which the securing members are engaged. 14 indicates a shaft rotatably mounted in each journal box 12 on which is mounted a roller 15 that traverses the flanges of the circular track made up of the channel beams 6 hereinbefore described. 16 and 17 designate bars connecting arcuate bars 10 and the tracks 9 respectively, and cross intermediate the track and over the center of the circular track formed by the members 6. 18 designate truss beams secured under the beams 1 at the middle of .each beam and having their intermediate ing a support for the crossed beams 1G, 17, and 18, and 19 indicates a pivot bolt engaging the beams 1G, 17, and 1S.

To accommodate trucks of different lengths, the rails 9 are extended at one of their ends at a distance beyond the supporting frame, and the extreme ends oit the extended portions are connected by a beam 19:t and an upright sill 20 to .torni a step to limit the movement et the truck on the rails. 2l designates a post at the outer end of each rail 9, and a brace therel'or, while 23 is a handle member supported by said post on each side and the outer ilange et each rail S), said handles 23 being designed lo be used iu turning the table.

It will be readily understood that because ol" the tact that the ditlerent parts ol. the improved turn table are secured together by bolts that can be readily removed that the device is capable ot portability and `to be set up wherever desired :l'or the purpose intended, and it will be clearly apparent that in operation a minimum amount of space is required to turn the truck and that the turning may be accomplished quickly, thus preventing interference with the ordinary road traliic that would otherwise be interfered with in turning the truc-k Where it is required to do so.

In order that the turn table may be .moved short distances Without necessitating knock ing it down provision is made to mount it on temporary rollers or casters as shown in Figures S and 9 in which 24: indicates the Wheel or roller journaled between arms 25 ternana on plate 2G, 2i' being lugs or pins on said plate QG that engage in openings 28 in the bottom flange of channel beams l, it being understood that provision must be made for the rollers or casters at each corner of the frame.

Vt'hat is claimed is i. A turn table comprising a rectangular frame, a circular track comprising semicircular segments secured together and secured within the rectangular frame, said circular track being oi channel construction and having' the llanges extending inwardly ot the circle, supporting members :tor the f object tu be turned comprising tlanged rails, arcuate .spacing members connecting said rails, and Wheels carried by said spacing members and traversing the flanges on the circular track.

2.. A turn table comprising a rectangular traine, a circular track enclosed by said ianlc, supporting members ii'or the object to be turned comprising ilangcd rails, arcu ate spacing members connecting said rails, a bar connecting said arcuate members, another bar connecting the rails and at right angles to the iirst mentioned bar, trussed bars connecting opposite sides of said rec tangular traine and crossed intermediate of their ends, a pivot connecting the crossed portions o'l said bars, and Wheels carried by said arcuate members and traversing said circulan' track.

In testimony whereof I affix my signature.

EARL L. GLAZE.
